HE220, HE260 Humidifier Installation Kit INSTALLATION INSTRUCTIONS
WELCOME
INSTALLATION
To the comfortable world of humidified air. When you use your Honeywell humidifier, you notice that your skin is not as dry, and that your scratchy throat and irritated nasal passages that aggravate allergies and asthma are steadily improving.
Preparing for the Installation
You have also taken the first step in reducing the zapping you create when you walk on your carpet and then touch your TV, computer, metal door knob or your pet. Your furniture and woodwork are also benefitting from the difference that humidified air makes.
Required Accessories (Included)
Be sure to identify all the required (Table 1) accessories (included) and make sure the appropriate tools are available before beginning the installation.
Table 1. Required Accessories.
Congratulations! You have just made a great investment in improving the comfort of your home.

Determining Best Location for Humidifier
Selecting Location for Sail Switch
• Select a location for the humidifier on the supply (warm air stream) or the return plenum. See Fig. 1. • Select a location for the bypass on the opposite plenum. The sidewalls of the humidifier are interchangeable to allow bypass duct mounting on either side of the humidifier. • Select a location that cannot damage the air conditioner A-coil during installation. • Select a location where the 6 ft (1.86m) of 6 in. (155 mm) duct provided is adequate to connect the humidifier to the bypass. — Do not locate the humidifier or bypass on a furnace body. — Allow adequate clearance in front of and above the humidifier so you can easily remove the cover to perform routine maintenance. — Mount humidifier at least 3 in. (78 mm) above the furnace body to allow adequate space for the solenoid valve and drain line. — Mount humidifier in a conditioned space to prevent freezing.
• Select a location for the sail switch in the cold air return duct where the sail is in the direct path of an unrestricted air stream. — Sail switch detects when furnace fan is operating. • Select a location where the air duct is at least 12 in. (305 mm) deep and 8 in. (203 mm) wide to allow operation of the sail without affecting the smooth flow of air in the duct. — Airflow at the location can be vertical (up or down) or horizontal.
IMPORTANT Mounting the S688 in warm air supply duct can reduce the sail life. Mount the switch at least 6 in. (152 mm) upstream from an elbow or junction, and at least 15 in. (381 mm) downstream from an elbow or junction. Locate the switch on the opposite side of the duct from the air entrance. (See Fig. 1-3 in S688 Installation Instructions.)
Selecting Location for Humidistat • Select a location for the humidistat on the return plenum or on the wall in the living space. — Mounting on the return plenum is the easiest installation for the control wiring circuit. For return duct mounting, the humidistat should be mounted upstream from the humidifier or bypass so that it is properly sensing the relative humidity of the living space. Locate the control at least 8 in. (203 mm) upstream from the humidifier in the return air duct. (See Fig 2.)

Selecting Water Supply Location Fig. 2. Selecting duct location for humidistat.
• Use either hard or soft water in the humidifier and either hot or cold water. The water flow rate, with the humidifier running, is 3.5 gal/hr (13 liters/hr) to flush the pad and provide moisture for evaporation. • Make sure that the 20 ft (6.2m) of feed water tubing provided is adequate to connect the water supply (saddle valve) with the humidifier solenoid valve.
Locating Closest 120V Electrical Outlet • Select location with access to an outlet. If not available, contact an electrician to have one installed. Make sure that the 20 ft (6.2m) of thermostat wire is adequate to reach from the humidifier solenoid, to the sail switch, to the humidistat, to the plug-in transformer in the outlet.
Locating Closest Floor Drain • Select location with access to a floor drain to provide drainage for air conditioner condensation and humidifier drainage. • If you do not have a drain available, we recommend that you install the Honeywell Whole House Drum or Disk Humidifier. • Make sure that the 10 ft (3.1m) of drain tubing is adequate to reach from the humidifier drain connection to the floor drain.

Sharp Edges Installation Hazard. Can cause personal injury. Wear gloves and safety glasses. Turn off power to the air handing system at the circuit breaker. Draw a level line on the plenum in the location chosen for the humidifier. (Leveling assures optimal humidifier performance.) Locate the template in the Humidifier Installation Instructions. Tape the template in position and trace around the template. Remove the template and carefully cut the rectangular opening. Disassemble the humidifier; remove the cover and take out the humidifier pad assembly. See Fig. 3.

Use 1/4 in. (6 mm) OD tubing and connect saddle valve to inlet side of the solenoid valve (see Fig. 9). a. Place brass compression nut over tubing. b. Install brass insert into end of tubing. c. Slide the plastic compression ring over the tubing. (Discard copper compression ring provided with valve.)
NOTE: To prevent leaking, use plastic (Delrin) sleeve rings with plastic tubing. Use copper sleeve rings only with copper tubing.
IMPORTANT Be sure to reconnect the water feed tube and ensure that the tube is not pinched or kinked.
d. Insert the tubing into the solenoid valve fitting and support the valve while tightening the compression nut.
16. Hinge the cover in place and secure with the thumbscrew located at the bottom of the cover.
NOTE: Do not over-tighten the compression nut. Moderate tightness prevents leaking. e. Repeat steps a. through d. for saddle valve fitting. f. Secure tubing with clamps provided.

TESTING HUMIDIFIER OPERATION
Run the two-strand thermostat wire from the humidifier to the transformer, from the transformer to the humidistat, and from the humidistat to the sail switch. Cut lengths of thermostat wire to reach between components, leaving adequate wire at both ends for connections.
Checklist ❑ ❑ ❑ ❑ ❑ ❑ ❑
Humidifier is level. Starter collar is secured with sheet metal screws. Summer shut-off damper is open (in winter position). Control wiring was reviewed using circuit diagram. Transformer is plugged in. Feed line has no kinks. Drain line slopes continuously down and ends at floor drain. ❑ Water hose inside humidifier is connected to PerfectFlow™ water distribution tray.
NOTE: Transformer, humidistat and sail switch can be wired in any order. 3. 4. 5. 6.
At the humidifier, connect the black and white conductors to the two black humidifer wires. At the transformer, connect both black conductors to the two transformer terminals. Use a wire nut to connect together the two white conductors. At the humidistat, connect both black conductors to the two humidistat terminals. Use a wire nut to connect together the two white conductors. At the sail switch, connect the black and white conductors to the Com and NO sail switch terminals (NC terminal is not used).
After installation use the following steps to check the humidifier operation: 1. Turn on the power and the water supply 2. Turn the H8908 Humidity Control to On and turn on the heat by setting the thermostat to 10ºF (6ºC) above room temperature.
IMPORTANT The furnace blower must be on in to activate the humidifier. 3. 4. 5.
